What are the cultivation methods for potted ginkgo trees?

The ginkgo tree is a tall tree of the Ginkgoaceae family. Its seeds are commonly known as white nuts (baiguo) and are a green health food. Nowadays many people grow ginkgo as potted plants, which look very attractive. Today the editor will share with you the cultivation methods for potted ginkgo trees.

1. Seed propagation

Seed propagation of ginkgo is mostly used for large-scale landscaping seedlings or for making clump-style bonsai. After harvesting the seeds in autumn, remove the outer seed coat and dry the seeds with the fruit coat still on. They can be sown in winter of the same year or in spring of the following year. Spring sowing must first undergo stratification with mixed sand to promote germination. When sowing, place the seed embryo horizontally in the sowing furrow, cover with 3-4 cm of soil and press firm. The seedlings can grow to 15-25 cm tall in the same year.

2. Potting and planting

Ginkgo trees can be propagated by cuttings, division, grafting and sowing. When potting, because the ginkgo tree is a deep-rooted species, a relatively deep flower pot should be used for planting. Planting is generally done in spring and autumn. It has low requirements for soil, but if you can use sandy soil rich in humus, loose and fertile, with good drainage, the ginkgo will grow even better.

3. Placement location

Potted ginkgo trees have requirements for their placement location. Although it is a light-loving species, it cannot be placed in a spot with long periods of direct sunlight. You must choose a spot with limited sunlight that is well ventilated and humid. In summer, avoid exposure to the sun and provide appropriate shade. Although the ginkgo tree is a cold-hardy species, in winter you should still bury the whole pot in the soil, as this is the safest way to overwinter.

4. Reasonable watering

Ginkgo trees like moist soil, but on no account should water accumulate in the pot. There is also particular care needed when watering ginkgo in winter. When winter temperatures are relatively high, water evaporates faster, so watering is generally done in the morning and evening. If the temperature is generally cold and the pot soil is moist, then there is no need to water.

5. Timely fertilizing

In winter, potted ginkgo trees can be given homemade organic fertilizer, which must be organic fertilizer such as decomposed soybean cake or barnyard manure. After entering spring and summer, the ginkgo tree enters its growing period, and it is more suitable to water it with human excrement or animal manure. This kind of fertilizer can promote leaf growth and keep the leaves a fresh green.

6. Shaping and pruning

Before the ginkgo tree buds in spring, pruning should be carried out once. Because its leaves are relatively large, the branches kept should be sparse rather than dense. For small and medium-sized bonsai, keeping 3-5 branches is enough. At the same time, according to the needs of the shape, the branches should be appropriately wired or pruned so as to reveal a trunk with a certain degree of twists and turns for people to admire.

7. Timely repotting

Generally, potted plants need repotting, and potted ginkgo trees are no exception. Potted ginkgo trees are generally repotted once every 2 years, and this needs to be done around the spring equinox. When repotting, note that the well-developed root system of the ginkgo tree can be appropriately shortened, then replace one third of the old soil with new soil. Base fertilizer should be placed at the bottom of the pot, as this is beneficial to the growth of the ginkgo.
